NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application led March 18. 1907. Serial No. 362,876.

`To all 'whom it 'may concern:

Be it known that I, ARTHUR W. SWAN- BERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and Stateof Minnesota, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.'

My present invention relates to non-refillable bottles, and has for its especial object to improve the same in the several parts hereinafter noted.

The invention consists of the novel devvices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings,which illustrate my invention,l like characters indicate to Fig. 2, but with the guard plate removed.l

The numeral 1 indicates the body of a bottle with the lower portion broken away, and the numeral 2 indicates the neck thereof. The neck 2 at its intermediate portion is expanded to form a chamber 3 which eX- tends down to an inset ledge 4f Below the ledge 4, the neck 2 is ,contracted to form a valve seat 5. A tapered cork 6 inserted into the neck 2 and into the chamber 3 thereof is adapted to close the passage through the valve seat 5, when the bottle is set upright. This cork 6 therefore operates as a plug valve. A stem 7, provided at its lower end with screw threads 7/ is adapted to be screwed into the top of the cork 6 and supported thereby. The stem 7, which is preferably made of glass, and rectangular in cross section, is provided near its upper end with a seat 8, and at its intermediate portion with a seat 9.

To prevent the cork 6 from being removed from the bottle, a so-called guard plate 10 of glass is provided. This guard plate 10- has cast on its under side an L-shaped arm 11. Said arm 1'1 is of such size as to loosely t within the seat 8 of the stem 7, and normally supports the guard plate 10 in a horizontal position.

A lock wedge 12 of glass, mounted in the seat 9 formed in the intermediate portion of the stem 7, is provided with a stop lug 13 for engagement with the lower portion of the seat 9, and is also provided with a stop shoulder 14 for engagement with the upper portion of the seat 9. The tapered portion 15 of the lock wedge 12 ynormally pressingv against the elbow of the L-shaped arm 11 holds the guard plate 10 in itsnormal or horizontal position.

vWhen the bottle is inverted, the weight of the guard plate 10 will be sufficient to withdraw the cork 6 from the valve seat 5, thereby permitting the free discharge of the liquid from the bottle. In case the cork 6 should stick in the valve seat opening 5, a tool with a bent end may be inserted through the opening 16 of the guard plate 10 and hooked to the under surface thereof, and then by lifting on the tool the cork may be removed.

To prevent the guard plate 10 from stopping up the neck ofthe bottle while the liquid is being discharged, the up er surface of said guard plate is provided wit a pair of lugs 17. These lugs 17 will rest against the upper surface of the chamber 3, thereby leaving a free passage for the liquid between the guard plate and the upper surface of said chamber.

To place the cork 6 within the valve seat 5, and the guard plate 10 within the chamber 3, said guard plate is turned into 'the position indicated by dotted lines in Fig. 1 By pressing the guard plate 1() toward the left,

and the lock wedge 12 toward the right, the

tapered end 15 ofthe lock wedge will enter a pocket 18 formed or pressed into one side of the arm 11. After the cork 6 is seated in the valve seat opening 5, the guard plate 10 may be turned into its normal or horizontal position, by pressing down upon the upturned portion thereof, with any suitable tool. The parts will then assume the positions indicated in Figs. 1 and 2. After said parts are in their normal positions, it willbe impossible for them to again assume the positions indicated by dotted lines in Fig. 1Q On account of the pocket 18 being located on one side of the arm 11 as best shown in Fig. 2, it 4 lines in Fig. 1, the tapered point 15 of thev lock Wedge Would strike against the bottom of said guard plate. On account of the stop shoulder 14, and the lug 13, it Would be impossible to remove the lock Wedge 12 from the seat 9. parts again into the positions indicated by dotted lines in Fig. 1 by passing a Wire between the guard plate 10 and the Wall of the chamber 3, the Wire Would strike the flange 4 and be deflected.

The device described is thought to be eilicient for the purpose had in view.

What I claim is 1. The combination With a bottle having a neck, an expanded portion forming a chamber and a valve seat, of a plug valve -coperating with said seat and having a projecting stem, a guard plate Within said chamber, supported by said projecting stein, and

In case any one tried to reset thel means for locking said guardplate to said projecting stem7 substantially as described.

2.l The combination With' a bottle having a neck7 an expanded portion forming a cl1amber and a valve seat, of a plug valve coperating with said valve seat and having a projecting stem formed With seats 8 and 9, a guard plate Within said chamber and having a depending arm mounted in said seat 8, and a lock Wedge mounted in said seat 9 and ene gageable with the arm to lock the same in said seat 8, substantially as described.

In testimony whereof I afliX my signature in presence of two Witnesses.

ARTHUR IV. SVVANBERG.
